Regarding the opposite sex, they're on a steep learning curve. In every other sense, they're geniuses. Join physicists Leonard Hofstadter (Johnny Galecki) and Sheldon Cooper (Jim Parsons) as they ponder black holes, chemical deviations, girls, and other mysteries of the universe in all 24 phenomenally funny episode of the Season Five. With Penny (Kaley Cuoco) and Leonard's relationship in uncharted terrain, Sheldon, Howard (Simon Helberg), and Raj (Kunal Nayyar) discover that the feminine mystique is something that cannot be easily graphed or calculated. As they muddle through relationship "bugs" and romance re-launches, they also discover it's nothing a good roll of the D&D dice or a paintball tournament can't solve.
Leonard and Sheldon are brilliant physicists, the kind of "beautiful minds" that understand how the universe works. But none of that genius helps them interact with people, especially women. All this begins to change when a free-spirited beauty named Penny moves in next door. Sheldon, Leonard's roommate, is quite content spending his nights playing Klingon Boggle with their socially dysfunctional friends, fellow Caltech scientists Wolowitz and Koothrappali. However, Leonard sees in Penny a whole new universe of possibilities ... including love.
